2013 KTM 250 SXF

The 2013 KTM 250 SXF comes with a completely new, even lighter engine and an updated injection system. With a new frame and new bodywork, it is ready to be a winner bike that dominates the 250 class, compete on other manufacturers such as Suzuki RM Z250, Yamaha YZ250F, Kawasaki KX250F, and Honda CRF250R. The modern frame design of lightweight, high strength, chrome-molybdenum steel section tubes guarantees an ideal mix of longitudinal and torsional stiffness, resulting not only in easy handling and precise steering behavior, but also in excellent ride stability, as on smaller and bigger SX model. The newly developed DOHC engine is the redesigned cylinder head with twin overhead camshafts and DLC-coated cam followers that actuate the titanium valves. The stroke-bore ratio has been defined as shorter-stroked for the benefit of higher peak power, with the new cylinder now boasting a bore of 78 mm (compare with previous model), hence providing space for larger valves. The engine also has a laterally positioned balancer shaft, which also serves as the drive wheel for the timing chain and the water pump. Check more detail specs and new features on 2013 KTM 250 SXF.

2013 KTM 250 SXF Features

Engine and Transmission – A new design without kick-starter, in a new engine case and manufactured in a die-casting process. Elastic and simultaneously high-strength, aluminium alloy provides additional damage protection for the engine. The Keihin engine management system with electronic fuel injection has been improved significantly, even more performance has been achieved with greater air flow through a new throttle body, featuring a 44 mm instead of a 42 mm port. The Throttle Position Sensor (TPS) is harder wearing and protected from stone impact with a plastic protector. Additional engine characteristics can also still be activated with an optional map-select switch on the handlebars.
Chassis and Suspension – The further improved 48 mm upside-down fork featuring closed-cartridge technology has been optimized with completely revamped settings for perfect harmony with the new frame and engine. CNC-machined from high quality aluminium, whereby the steering characteristics and hence the responsiveness of the fork have been noticeably improved. The WP monoshock and linkage system, it excels with its completely revamped settings for improved damping, more traction and even higher reserves against bottoming out. The wheels are fitted with lightweight, CNC-machined hubs and high-end EXCEL rims, plus new, black-coated spokes with aluminium nipples, guaranteeing the highest levels of stability while keeping weight to a minimum. The Pirelli Scorpion tires stand for excellent traction and good performance on 2013 KTM 250 SXF.
